In any election for state office, members of the legislature, justices of the
supreme court, judges of the court of appeals or statewide initiative or referendum the
attorney general may enforce the provisions of this title through civil and criminal
actions. In any election for county, city or town office, community college district
governing board, judge or a county, city or town initiative or referendum, the
appropriate county, city or town attorney may enforce the provisions of this title
through civil and criminal actions. In any special district election, the county
attorney of any county in which the district or a portion of the district is located or
the attorney general may enforce the laws governing such election.
I believe this is a civil matter that must first be set forth for action to the Arizona Attorney Generals Office:

Contact them for more information on how to file a petition or complaint, which must be set forth in an appropriate manner that applies to the statues (referenced above) and meets evidenciary and due process legal statutes.
This is doable without an attorney.
Examples exist publicly for other pleadings.
